Technology for Making Leakproof Structures Based on Carbon–Carbon Composites of the Uglekon Type

Abstract

Processes for making a new class of hermetic carbon–carbon composites that are stable under extreme service conditions – high temperatures and aggressive metallic melts and chemicals – have been researched and developed. Researchers have developed a functional flow diagram for making such materials and have determined its parameters in each technological conversion. The physico-mechanical properties of two types of carbon load-bearing substrates are compared and the preferred type of substrate is chosen. A study is made of the main kinetic parameters of the saturation of the substrate and the slip sublayer with pyrocarbon, which results in the formation of a hermetizing pyrocarbon coating on the sublayer.
